Why Does the Coolant Keep Decreasing?

[McKai]

There are three main reasons for coolant loss: 1. Excessive natural consumption: Engine oil or cooling system issues causing excessively high engine temperatures, leading to increased coolant consumption. Solution: Use high-quality engine oil and regularly inspect the vehicle's cooling system. 2. Coolant entering the cylinders: Damaged intake manifold gaskets or cylinder head gaskets can allow coolant to enter the combustion chambers where it evaporates. Solution: Replace the faulty components. 3. Radiator cap, radiator, or water pump leaks: Visible coolant leaks can often be identified by water stains under the chassis or radiator. Solution: Replace the damaged radiator cap, radiator, or water pump as needed.
